LlNOTYPE-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 790,447, dated May 23,1905.

Application iiled September 1, 1904:. Serial NoK 223.079.

To tu whom, it may concern:

curved guiding-channels, through which theyl descend into the upper-endof an inclined magazlne. The magazine consists of parallel plates havingtheir opposing faces grooved to receive and guide the upper and loweredges of the matrices. The intermediate channels or guides delivering tothe upper ends of the magazine are formed in a hinged frame, technicallyknown as the channel-entrance. This frame may be turned backward inorder to give access to the upper end of the magazine and theadjacentparts of the overlying distributer. It sometimes happens that when thechannel-entrance is turned backward a matrix just released or on thepoint of being released will pass down into the upper end of themagazine and fall upon its side instead of properly entering theguiding-grooves at its edges. These matrices lying on their sides willslide downward into the magazine until arrested by the matrices therein.Their eX- traction is attended by a loss of time andfrequently bydisarrangement of other matrices.

The object of my invention is to prevent say, between the pathstraversed by the upright matrices-a series of vertical pins so locatedthat while they permit the matrices to descend in their proper positionsthey will arrest the fallen matrices. These guard pins or stops may bemade in any suitable form and applied in any suitable manner, the

. the magazine.

only requirement being that they shall prevent the matrices which lie ontheir sides from descending into the body of the magazine. In thedrawings I have shown a series of stop-pins secured at their upper endsto a bar, so that they may be thrust downward through a series of holesin the top plate of This arrangement admits of their being instantlyWithd rawn when the interior of the magazine is to be cleaned by abrush, according to the ordinary practice.

Referring to the drawings` Figure 1 repre-'l sents a verticalcross-section from front to rear through the upper end of the magazine,the channel-entrance, and thedistributer with my improvement appliedthereto. Fig. 2 is a perspective view of the foregoing parts lookingfrom the rear, the channel-entrance being shown in its open position andall parts shown -in section at one end. Fig. 3 is a top plan til theyarrive over their appropriate magazine-channels.

C C are the parallel horizontal screws which engage the edges of thematrices for the purpose of carrying them along the distributerbar.

D represents the channel-entrance, having its upper surface divided by aseries of parallel plates d into a series of channels or passages, intowhich the matrices fall when delivered by the distributer-bar. Thischannel-entrance is extended downward and forward in a curved line, sothat the matrices may be delivered from its lower end directlyv into theupper ends ,of the magazine-channels.

E represents the magazine, consisting of the top and bottom plates e ande', spaced a suitable distance apart and provided on their opposingfaces with the grooves or channels e2 to receive and guide the upper andlower edges of the descending matrices.

.So far as described the parts are of the ordinary construction andarrangement and operate in the ordinary manner.

The channel-entrance stands normally in the position shown in Fig. l,its upper edge in position to receive the matrices from the bar and itslower edge in position to deliver them into the magazine. Under normalconditions each matrix passing from the channel-entrance D into themagazine will be held and guided at its upper and lower edges, and thusmaintained in an upright position, as shown in Fig. 2. When, however,thechannel-entrance is swung backward on its hinge or opened, as shown inFig. 2, a matrix will sometimes fall upon its side and enter the upperend of the magazine, as shown in the middle of the magazine in Fig. 2,its upper and lower edges failing to enter the grooves in the plates. Itis to arrest these matrices in the upper end of the magazine and in suchposition that they may be readily removed that my improvement isdesigned. In the form shown it consists of a series of upright pins G,secured to -f a bar g, overlying the magazine and extending thencedownward through holes in the top plate to the upper surface of thebottom plate, or practically so. These pins are located at pointsbetween the grooves or channels, or, in other words, between the pathspursued by the matrices, so that the matrices standing on edge in theproper position may pass between them without interference. The distancebetween the pins is such, however, that it is impossible for a matrixlying on its side to pass between them.

are consequently arrested at or near the upper The fallen matrices endof the magazine, so that they maybe conveniently and instantly' removed.

The essence of the invention resides in the employment of uprights orstops in any form which will permit the passage of the upright matrices,but arrest those which have fallen. They may be either removable, asshown, or they may be located permanently in position.

Having described my invention, what I claim isl. In a linotype-magazine,comprising a pai r of grooved plates to guidethe matrices on edge, stopsarranged to arrest the fallen matrices.

2. In a magazine for a linotype-machine,the combination of two groovedplates adapted to 'guide the edges of the matrices, and stops, G,

to prevent the passage of the fallen matrices.

3. The combination with a magazine comprising upper and lower groovedplates, a removable bar, g, provided with a series of stoppinsprojecting into the magazine to arrest the fallen matrices.

4. In a linotype-magazine having grooves to guide the opposite edges ofthe matrices, removable stops to arrest the fallen matrices.

5. A matrix-stop for application to a linotype-maehine, consisting of abar adapted to extend transversely across the upper end of the magazine,provided with pins of suitable length to project downward into themagazine to the surface of the lower plate, in order to arrest thefallen matrices lying on said plate.

In testimony whereof I hereunto set my hand, this 24th day of August,1904, in the presence of two attesting witnesses.

ROBERT F. MERCER.
